SPRING-TIRE.

To au whom it muy amm:

Be it known that I, CHARLES P. Roeien, a citizen of the United States, residin at Boulder, in the county of Boulder and tete of Colorado, have invented new and useful Improvements in Spring-Tires, of which the following is a s .ifiention The invention reliies to tires, and more particularly to the class of spring tires for vehicles. f

T ie primary object of the invention is the previsioni of a tire in which the same may be conveniently and readilly mounted upon the telly of a vehicle whee and that will possess the requisite amount of resiliency and durability.

Another object of the invention is the provision of a tire in which the body por tion thereof is supported upon resilient nieniherswhich permit the yielding of the body` solas to absorb shocks and jars incident to @he travel of a vehicle wheel, and that will obviate the puncturing` of the tire, thereby increasing the life of the same.

A further object of the invention is the provision o f a tire in which the body thereof is formed from metal, the same being provided with'a resilient tread, either of rubber or leatheig, the body being supported upon a pluralityof springs, and sustained spaced from the felly, so as to possess the requisite resiliency, when in service.

A stillfurther object of the invention is the provision of a tire which is simple in construction, strong, possessing the characteristics of an ordinary pneumatic tire, and that is reliable and cltieient in operation, and inexpensive in manufacture.

Y'Vith these and other objects in view, the invention lconsists in the construction, combination and arrangement of parts, as will he hereinafter more fully described, illustratod in the accompanyinp,r drawings, and p'ointed out in the claim hereunto appended.

in the drawings: Figure 1 is a side elevation of a vehicle Wheel` parts being broken away. with the tire thereon constructed in accordance with the invention. fragmentary vertical longitudinal sectional view through a portion of the tire and vehicle Wheel. Fig. il is an enlarged vertical transverse sectional view. Fig. 4 is a plan view, looking toward the tread of the tire, the saine being partly broken avi/ay.v` `lig. 5 is a side elevation of a pair of spriliflf,l nicmboi's removed from the tire.

Similar reference characters indicate corresponding parts throughout the several views of the drawin Referring to the rawings by numerals, 5 designates generally a vehicle wheel, which is of the ordinary welhknown construction, having the usual rim 7, upon which is mounted the tire, presently described.

The spring tire comprises a metallic band 7', the same being adopted to fit upon and surround the felly 6 of the vehicle wheel, and has its ends outturned to. form parallel years 8, the same being provided Withsuitable alining openings or perforations, through which is passed a bolt member 9,

the band 7 upon the felly of the vehicle wheel. The said felly ma be suitably cham neled to receive the banal; so as to prevent ,any lateral displacement of the same thereon. At intervals throughout the diameter of the band 7 are formed suitable openings, through which are passed bolt members lf) having the usual heads which are adapted to engage in counter seats formed in the inner face of the band 7', so that the said heads of the bolt members will lie Hush with the inner face of said band, when engaged in the openings therein.

Mounted upon the bolt members 10 are transversely disposed clamping plates or ends of oppositely extending spring members 12, the outer ends of which areicoiled, as at 13, while the inner ends of the said spring members are upturned, as at 14, to engage in suitable openings formed in the blocks or plates 11, the inner faces of the latter being formed with grooves providing seats 15 for the spring members 12, and upon the tightening of the bolt meu'ibe'isilO, the said clamping plates or blocks l1 will securely fasten the springinembers thereto.

Supported by the spring members 12 is an annular tire body 16, the same being formed with an annular channel 17, at its inner side, into which project the coiled ends 1,3 of the spring members, and throii h these coiled ends are passed transversely disposed bolt members 1S, the latter being engaged in oppositmside walls of the said tire body 16, thereby connectingthe latter to the coiled ends of thex spring members.

The tiro body i6 is preferably constructed from aluminum, although it may he made from any other suitable metal or material,

which, when tightened, will securely fasten blocks 1,1, in which are engaged the inner` and has formedvin `its outer side an annular groove 19, in which is eng-ageda resilient tread 20, preferably of rubber, although the same may be made from leather or other suitable elast-ic or resilient material. It will be evident that the tire body 1G will yyield` when passing over an obstruction or any irregularity in the ground, and can netbeeome punctured or will not burst, thereby increasing the life of the tire. The tire constructed as hereinbefore stated will possess all of the characteristics of an ordinary pneumatietire, yet will have the advantage of greater durability and strength, with the required elasticity for eustoinaryserviee.

lVhatis claimed is:

A spring tire of the class described comprising a band secured to the felly of a wheelr'relatively spaced clamping blocks,

bolts passing through saidiband and blocks 20 tosecure theA blocks to the outer side of the band, said blocks having a pair of L-shaped openin s on each side of said bolt, the openings o each pair being relatively spaced, a

pair of relatively spaced springs located on 25 each side of each block, said springs being provided With curved bearing portions resting on the `outer side of the band and hav- 'ing their inner ends bent .upwardly and en` gaglng in said openlngs, said springs having 3u outwardly coiled 'outer ends, and a tire eonnected with the coiled ends of said springs.
